1. What is the Diamond Weight Formula?

The diamond weight formula calculates the carat weight of a diamond based on its dimensions and specific gravity. This formula provides an accurate estimation of a diamond's weight without physically weighing it.

2. How Does the Calculator Work?

The calculator uses the diamond weight formula:

\[ Weight = \frac{Length \times Width \times Depth \times Specific\ Gravity}{200} \]

Where:

\( Length \) — Diamond length in millimeters (mm)
\( Width \) — Diamond width in millimeters (mm)
\( Depth \) — Diamond depth in millimeters (mm)
\( Specific\ Gravity \) — Diamond's specific gravity (typically 3.52)

Explanation: The formula calculates the volume of the diamond and multiplies it by the specific gravity to determine weight, then converts to carats.

3. Importance of Diamond Weight Calculation

Details: Accurate diamond weight estimation is crucial for valuation, pricing, certification, and comparison shopping in the jewelry industry.

4. Using the Calculator

Tips: Enter precise measurements in millimeters. Use calipers for accurate results. The standard specific gravity for diamonds is 3.52, but this can be adjusted for different gemstones.

5. Frequently Asked Questions (FAQ)

Q1: Why is specific gravity important in the calculation?
A: Specific gravity accounts for the density of the material, which varies between different gemstones and affects the weight calculation.

Q2: How accurate is this calculation compared to actual weighing?
A: With precise measurements, this formula provides a very close approximation, though physical weighing remains the most accurate method.

Q3: Can this formula be used for other gemstones?
A: Yes, but you must adjust the specific gravity value according to the specific gemstone being measured.

Q4: Why divide by 200 in the formula?
A: The division by 200 converts the result from milligrams to carats (1 carat = 200 milligrams).

Q5: What are the most common measurement errors to avoid?
A: Common errors include using inaccurate measuring tools, not measuring at the widest points, and using incorrect specific gravity values.
